Test your SKILL Knowledge: Understanding Variable Scope

PCBTech

Examine this code sample and predict what will be printed to the console:

globalVar = "Global Variable"

procedure(testScope()
  localVar = "Local Variable"
  printf("In testScope Global: %s Local: %s \n" globalVar localVar )
  let((globalVar)
    globalVar = "Modified"
    localVar = strcat(localVar " with Changes")
    printf("Inner Global: %s Local: %s \n" globalVar localVar )
  )
  printf("After let Global: %s Local: %s \n" globalVar localVar )
)

printf("Outside testScope Global: %s \n" globalVar )
testScope()
printf("After testscope Global: %s Local: %s \n" globalVar localVar )

 

How should we change the code to correct variable visibility both inside and outside of the procedure scope?
